To @ZZ whom it may concern.-

Be it known that I, EDWIN D. HCCRACKEN, of Alpine, in the county ofBergen and State of New Jersey, have invented a new and usefulImprovementin lliachinestor Making Paper Tubes, of which the followingis a specification.

My invent-ion relates to a machine which in some respects resembles anordinary lathe, in

1o that it is provided with head and tail spin dles for supporting anddriving a mandrel, and by which thin paper from a reel and in a strip ofconsiderable width may be wound spirally and continuously from end toend of the mandrel to form a tube of proper 'thickness, paste or otheradhesive substance being employed to produce adhesion between theoverlapping and superposed spiral convolutious. p

2o I employ in connection with head and tail spindles for supporting arotating mandrel, a rotary feed-shaft and a main sliding carriageoperated thereby and caused to travel along shears or ways similar tothose of a lathe.

Upon the main sliding carriage I support a rotary carriage or turn-tableand a paper reel or drum, which is mounted to rotate in a substantiall yvertical plane on the rotary carriage or turn-table, and has itsdiametrical 3o and axial center substantiallyin line with the center ofthe rotary carriage or turn-table. lVhen the rcel is thus arrangedrelatively to the rotary carriage, the carriage and reel. may be readilyadjusted to `give the paper adirection oblique to the mandrel, either inone direction or the other, from a central line, and thus bind itspirally upon the mandrel from either end alternately toward the otherend. Although the rotary carriage or turn-table 4o may be considered assupported upon the main sliding carriage, it is directly mounted upon acarriage which is 'fitted to slide onthe main carriage and transverselyto its line of movement and to the length of the mandrel,

and the rotary carriage or turn-table may be formed with a circle otworin-teeth, with which engages a tangential. worm or screw for shittingit.

I also employ a paste-applying roll or rolls,

5o which is orare pressed by springs against the paper tube on themandrel during'its formation, and preferably the paste-box, in which therolls are journaled, is guided in a saddle iitted upon the main slidingcarriage and is supported in said saddle by springs. I here use the termpaste-box and paste-applying roll in a generic sense, thereby meaning toinclude a box and roll for applying any ad hesive substance.

I also employ a pressure-roll, which bears 6o upon the top of the tubeduring its formation and produces the firm union of thespiralconvolutionsby means ot the adhesive substance and presses andconsolidates the paper. This roll is preferably journaled in a yoke,which is adapted to turn and also to rise in a horizontal arm, which isfulcrumed upon a post at the back of the machine and is capable ofswinging horizontally, so as to bri ng thepressure-roll to any desiredposition lengthwise ot' 7o the mandrel, and I also employ parallel connections on opposite sides of thisarm and extending to opposite ends ofthe roll, so that during the swinging movement of the arm the roll willalways be maintained parallel with the mandrel.

I also employ a post having a disk-cutter mounted upon it and provide asocket on each side of the upper sliding carriage for receiving the postand to enable it to be used for 8o cutting oit first one end and th-cnthe other of the paper tube.

The head and tail spindles maybe provided with suitable centers forsupporting the mandrel, and the center upon the head-spindle may have alongitudinal groove, with which engages a rib secured to one side otthehollow mandrel, and through which rib and groove the mandrel isdriven positively by the headspindle. 9o

For imparting motion to the'main sliding carriage, I prefer to employ anordinary feedshaft, which is geared to the head-spindle, S0 as to rotateat any suitable speed., and this feed-shaft has mounted upon it, withinthe sliding carriage, reverse bevel-wheels having clutch members formedintegral therewith, and the feed-shaft also has upon it movable clutchmembers having groove and spline or feather connections with the shaft.Both the roo reve rse bevel-wheels are in constant gear with a thirdwheel, which in turn andthrough suitable gearing transmits motion in onedirection or the other to a wheel which gears with a rack on the underside of the bed, and by the engagement of this wheel with the rack thesliding carriage is moved in one direction or the other at a very quickspeed as compared to the feed of a lathe.

The invention consists in novel combinations of parts, which arehereinabove brieliy referred to and hereinafter described, and pointedout in the'claims.

ln the accompanying drawings, Figure l is a side elevation, and Fig. 2 aplan, of a machine embodying my invention, a portion of the length ofthe machine between the head and tail sockets being broken away toreduce the size of the drawing. Fig. 3 is an end View of the machine,including the gearing whereby the feed-shaft is operated. Fig. 4 is atransverse section of the machine, upon a plane extending through themain sliding carriage. Fig, 5 is an elevation and partial section of thepressurcroll and the paste-roll and paste-box,incltidiiig a saddlesupporting the pasteebox and applied to the main sliding carriage, and asectional View of a portion of the gearing in the main sliding carriageupon about the plane indicated by the dotted line fn,Fig. 4t. Fig. 6 isa horizontal section upon about the plane indicated by the dotted liuey/y, Fig. 4, of the main carriage and the appurtenances or gearingconnected therewith. Fig. 7 is a vertical section, and Fig. S ahorizontal section, showinga portion of the rotary carriage or turntableand the transverselysliding carriage which supports it. Fig. O is adetail'view illustrating the center, which is upon the head-spindle, andthe means employed for imparting motion, therefrom to the mandrel; andFig. 10 is an elevation of a cutter operating upon the paper tube forcutting off its end, and which is supported from thetransversely-sliding carriage on which is the turn-table or rotarycarriage.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the bed, and Z) the tracks, ways, or shears, such as areordinarily provided upon a lathe. At one end of the bed is mounted ahead-stock B, in which is journaled a head-spindle orlivespindle C,having a cone-pulley (12, and on the opposite end of the bed is fixed atail-stock B', in which is journaled the usual tail-spindle C.

D designates a mandrel, which usually consists of a tube of metal fittedupon the centers c c and the live center c, or the center upon thehead-spindle C may have a longitudinal groove c2, which receives a ribor tongue cseeured to one side of the mandrel. Through this groove andrib or tongue the live-spindle C transmits rotary motion to the mandrelI).

At the front of the machine extends a feedshaft E, which is journaled insuitable 4bearings e, and through a suitable train of gears thelive-spindle C transmits motion to this feed-shaft. In this example ofthe invention the train of gears comprises a pinion or wheel c upon thelive-spindle C and wheel e? upon the eedshaft, and the intermediatewheel e3, which engages with both the. wheels e e2 and is journaled upona stud secured in the lever E', fulcrumed upon the feedshaft E. Theleveris provided with a slot et, in which the stud c5, on which the wheel c3is journaled, is adjustable, and is likewise provided with an arc-shapedslot e, through which passes a clamping-bolt e7, and by which the leverE may be adjusted and held at any desired angle to the horizontal. Thetwo slots e6 e4 provide for introducing a larger or smaller wheel inplace of the wheel e3, and therefore provide for imparting a slower orquicker mo tion to the feed-shaft E.

The machine comprises a main sliding carriage F, which, as best shown inFig. et, is snpported to slide freely upon't-he tracks or ways b, andwhich is moved to and fro along' the mandrel D by mechanism set inmotion by the feed-shaft E.

The mechanism for operating the carriage is best shown in Fig. 6.

On the shaft E are fitted reverse bevelgears ff', both of which engagewith the bevel-wheel f2, and which also comprise clutch members ffl. Thebevel-gearsff are held in proper position to engage with the wheel f2 bystuds f5, secured in the carriage F and engaging suitable grooves f inthe gears and clutch members. On opposite sides of the gears and clutchmembers f f are .fitted sliding clutch members f7 fs, which havea grooveand spline or feather engagement with the shaft E, so as to receivepositive rotary motion therefrom and so as to permit their sliding alongthe shaft.. The sliding clutch members f7 f8 may be operated by cams oreccentrics, which consist of pins f, set eccentrically in disks, whichare upon short shafts or studs flo, as best shown in Fig. 6, and theseshort shafts or studs fw are provided at the front of the carriage withhandles f 11.

As shown in Fig. G, the sliding clutch member f7 is adjusted intoengagement with a companion clutch memberfg, which forms a part of thegear f, and thereby the gear f is rotated and transmits its motion tothe gear f2, and at the same time the movable clutch member f8 is slidout of engagement with the clutch member f4, and the wheel f and clutchmember f4 are free to rotate idly by their engagement with the wheel f2.

Upon the under side of the bed is a longitudinal rack h, and 7Ldesignates a spur wheel or pinion, which is mounted upon a stud in thecarriage and engages with this rack. Gearing with the wheel or pinion his a second wheel or pinion h2, which is upon the short shaft h3,supported in suitable bearings in the carriage, and at the outer end ofthis shaft is a wheel 7a4, which is geared with the pinion 71.5 on thesame short shaft h6 to which the bevel-wheel f2 is attached.

Frein the above description it will be un- IOO IIO

derstood that the Wheel f2 will be rotated in one direction or theother, according to whichever of the wheels f f transmits motion to it,inasmuch as they engage with its opposite sides, and by the rotation ofthe wheelj"2 the train of gears 7i5 7L'l 7L2 7L Will be rotated, and bythe engagement of the wheel 7i with the rack 7L the carriage will bemoved at the desired speed in one direction or the other along thetracks or Ways b.

I have also represented on the carriage F a short shaft or spindle 707,provided on the front of the carriage with a handle hs and provided onthe inner end With a wheel 7L, which engages with the rack 71, and bythis handle 7L8 and wheel 7L" the carriage may be moved rapidly alongthe tracks or Ways when both the movable clutch members f7 f3 areadjusted to the position of the clutch member 2o f7 in' Fig. G.

H designates a carriage, which is mounted directly upon the maincarriage F, and by means of the screw II', provided with the hand-wheelat the front of the machine, may be slid or shifted upon the carriage Fin a direction transverse to the length of the .mandrel D, along agibbed Way or tongue 7N), upon the main carriage. The transverseadjustment of the carriage H provides for vary ing the distance from thepaper-reel I to the mandrel D, as may be desired when spirally windingpaper upon mandrels I) considerably larger than that here shown. Therotary adjustment of the carriage Il2 and the sliding adjustment of thecarriage H also combine to attord provision for laying the paperspirally upon the mandrel D at exactly the desired angle.

H2 designates a rotary carriage or turn-table, which is mounted in thetransverse carriage II, and which is constructed with a circle ofworm-teeth 71,11, and 7N designates a tangential shaft or key, on whichis a Worm 7tlg, engaging with this circle of gear-teeth. The projectionon the carriage H2, on which are formed the Worm-teeth 7L, is receivedin a cavity in the transverse carriage Il', and by turning theworm-shaft 7L12 the carriage O1' turn-table Il2 may be rotated to theextent desired. The carriage H2, although supported directly androtatable on the transverse car riage H, may be regarded as supportedfrom the main sliding carriage F.

On the rotary carriage or turn-table II is a standard t', supporting asuitable shaft I, to which is fixed a paper reel or drum I, and theshaft I and standard t' are so arranged that the diametrical and axialcenter of the drum I is directly in line with the center of theturn-table H2, and as the turn-table is rotated the angle at which thestrip of paper is delivered from the reel I upon the mandrel is varied,and the strip of paper may be delivered at an angle on either side of aplane directly transverse to the mandrel by shifting the rotary carriageor turntable H2 tothe desired position.

On the shaft I, I have also represented a brake Wheel or disk 97,011which acts a springactuated brake-shoe i2, movable vertically by theaction of the spring in the standard ff, so as to retard the rotation ofthe reel I and offer a su flicient resistance to the unwinding ot' thepaper to produce the smooth-laying under tension of the paper upon themandrel D.

To secure the firm adhesion of the spiral convolutions of paper, Iemploy a paste-box J, which contains paste or other adhesive material,and in which are journaled a paste roller or rollers J. In this exampleof the invention, two rollers bearing upon the paper tube Which is beingformed and arranged on opposite sides of the center of the tube are`employed7 and I may employ springs for maintaining the roller orrollers, pressed against the paper tube, which is Wound on the mandrelD. In the present example of the invention a saddle J2 is fitted to thedovetailed proj ection 7am at the top of the carriage F, and containssockets j, which receive down Wardly projecting stems j ou thepastetrough J, and these sockets contain springs j?, which bear upon thestems and thereby hold the roller or rollers J against the paper tube bypressure transmitted through the paste-box J.

To consolidate the paper and produce the firm union of its severalconvolutions by means of the adhesive substance, I employ apressure-roller J 3, which is in this example of my invention journaledin the yoke J, suspended from a horizontal arm J5, Vwhich is mountedupon a post J6 at the back of the machine. As represented, the post issecured in place upon the sliding carriage F by bolts jig, which passthrough slots j and provide for the adjustment of the post toward andfrom the mandrel D. maintained in vertical position and prevented fromfalling on the post J is free to turn thereon and is supportedvertically by a collar 17"", and the roller-yoke ,Il has a stem je,which is adapted to turn and rise in the end of the arm Consequently itWill be seen that the pressu1e-roller J 3 bears upon the paper tube witha force due to its Weight and to the Weight of its yoke J 1, and is freeto rise slightly and still maintain a uniform pressure as the paper-tubeincreases in size due to the winding of the strip upon it. I have hererepresented upon the post J6 a cross-piecef, from opposite ends of whichparallel connections jS extend to and engage with the roller J3 or withthe opposite ends of the yoke J4, and which serve to maintain the rollerJ3 in position parallel with and above the mandrel D, notwithstandingthe angle to which the arm J5 is adjusted.

After the tube has been formed upon the mandrel it is desirable to cutoff its ends truly, and to do this I employa rotary or disk knife 71:,which is mounted in a standard 7c', and I provide thetransversely-sliding carriage H TOO The arm J5, although it is IIO withsockets 7a2 at opposite sides, as best shown in Fig. 2, into either ofwhich the post 7o may be inserted in order that provision may beafforded for cutting off one end of the tube and then the other. Afterothe tube is thus completed and cutoff at the ends the mandrel D may beremoved from it by any desired v method.
